While I'm finding Cahill's analysis of the differences between Sumerian/Semitic religious practices and the embryonic Abrahamic faith very good. When Cahill moved forward to the Exodus, he's using the pop culture version in which Ramses II is the Pharaoh who opposed Moses, a mistaken belief by many Christians due to not carefully reading the Old Testament and the facts we know of Egypt in the 19th Dynasty.
P.S.- For those wondering, Amenhotep II (of the 18th Dynasty) is mostly likely the Pharaoh of the Exodus. (Akhenaton is his great-grandson.)
